### 7.3.3.1. The "ftp" and "tftp" access-types

An access-type of FTP or TFTP indicates that the message body is accessible as a file using the FTP [RFC-959] or TFTP [RFC-783] protocols, respectively. For these access-types, the following additional parameters are mandatory:

          NAME -- The name of the file that contains the actual body data.

          SITE -- A machine from which the file may be obtained, using the
          given protocol. This must be a fully qualified domain name, not a
          nickname.

Before any data are retrieved, using FTP, the user will generally need to be asked to provide a login id and a password for the machine named by the site parameter. For security reasons, such an id and password are not specified as content-type parameters, but must be obtained from the user.

In addition, the following parameters are optional:

          DIRECTORY -- A directory from which the data named by NAME should
          be retrieved.

          MODE -- A case-insensitive string indicating the mode to be used
          when retrieving the information.  The legal values for access-type
          "TFTP" are "NETASCII", "OCTET", and "MAIL", as specified by the
          TFTP protocol [RFC-783].  The legal values for access-type "FTP"
          are "ASCII", "EBCDIC", "IMAGE", and "LOCALn" where "n" is a
          decimal integer, typically 8.  These correspond to the
          representation types "A" "E" "I" and "L n" as specified by the FTP
          protocol [RFC-959].  Note that "BINARY" and "TENEX" are not valid
          values for MODE, but that "OCTET" or "IMAGE" or "LOCAL8" should be
          used instead.  IF MODE is not specified, the default value is
          "NETASCII" for TFTP and "ASCII" otherwise.
